Editing Stratus cloud (section)

=== Genitus mother clouds ===
'''Stratus cumulogenitus''' clouds occur when the base of cumulus clouds spreads, creating a nebulous sheet of stratiform clouds. This can also occur on [[nimbostratus cloud]]s ('''stratus nimbostratogenitus''') and on [[cumulonimbus cloud]]s ('''stratus cumulonimbogenitus'''). Stratus fractus clouds can also form under the base of precipitation-bearing clouds and are classified as pannus clouds. Stratus clouds may also form from formation mechanisms that are not typical for the cloud type, for example, '''Stratus homogenitus''', which are stratus formed by human activity, '''Stratus cataractagenitus''', which are formed from the spray of [[waterfalls]], and '''Stratus silvagenitus''', which are formed by evaporation or [[evapotranspiration]] occurring in a forest.
